Core Chemistry 14 - 16. Collecting and testing gases. This page looks at how you can collect and test samples of hydrogen, oxygen, carbon dioxide, ammonia and chlorine in the lab. It looks at four simple ways of collecting gases - over water, downward into a test tube or gas jar, upwards into a test tube or gas jar, and into a gas syringe.
Tubes are the ‘special agents’ among gas detecting devices: They detect over 500 different hazardous substances and measure even the most minute concentrations precisely and reliably – under the right conditions. Here are some tips on how to use Draeger tubes.
Tests for gases. There are several different tests to detect and identify gases and the. ions. in compounds. It is important that the test for any gas or ion is unique. The results of a test must...
